Weak or fluttering flames on multiple burners? Your gas pressure regulator stabilizes fuel supply to ensure consistent flame performance across all burners.

Secures your cooktop to the countertop from below. Includes brackets and hardware. Replace if worn, deformed, or screws are damaged or missing.

Foam seal tape creates a tight seal between your cooktop and countertop to contain spills and provide heat isolation. Replace when adhesive weakens.

The Screw is an OEM part for Bosch gas cooktops and ranges. It anchors the surface burner head assembly onto the cooktop surface.

Causes can be stripped threads or overall wear from repeated heating/cooling cycles. Exposure to cooking spills or impacts may also deteriorate the screw head over time.

Symptoms of a bad burner head screw include:

• A burner detaching from the cooktop surface entirely
• Excess movement or instability of burner heads when in use
• Gas leaks reported around the burner head connection points

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.

This thermocouple is the flame-sensing safety switch used on gas ranges/ovens. It detects the pilot or burner flame so the gas valve only stays open when a flame is present, helping restore reliable ignition and safe operation. What it does:

• Senses the presence of a pilot or main burner flame and signals the gas valve to stay open
• Stops gas flow when a flame is not detected to prevent unsafe gas buildup
• Common symptom fix: oven or range won't stay lit or the pilot won't remain lit
• Replaces a worn or damaged flame sensor to restore normal ignition behavior

• Turn off gas supply and electrical power before starting any work
• Position the thermocouple tip so it is properly seated in the pilot flame; avoid excessive bending or kinking of the tube
• Use correct fittings and tighten connections securely; inspect for gas leaks after installation
